2.3 Patent Challenges and Exclusions

• Pure algorithms without hardware linkage are excluded (Section 3(k))
• Discoveries of naturally occurring substances are excluded (Section 3(c))
• Methods of human manipulation or biological processes may be excluded (Section 3(j))

Battery technologies, being engineering and chemical innovations, fit comfortably within patentable criteria.

2.4 Patent Opposition

Competitors may challenge patents through:

• Pre-grant opposition
• Post-grant opposition

This is common in the EV and advanced-material sectors.

3. Trade Secret Protection

Trade secrets are crucial because many battery innovations involve sensitive manufacturing know-how that is not easily detectable via reverse engineering.

Key trade secrets for battery companies include:

• Electrode manufacturing processes
• Coatings and slurry formulation techniques
• BMS hardware + software algorithms
• Cell formation/aging recipes
• Testing & grading algorithms
• Vendor sourcing strategies and quality standards
• Process controls for moisture, contamination, and temperature

Since India does not have a dedicated Trade Secrets Act, protection comes from:

1. Non-disclosure agreements (NDAs)
2. Employee confidentiality & non-compete clauses
3. Vendor and OEM confidentiality provisions
4. Cybersecurity and internal access control policies
5. Trade-secret governance programs

Trade secrets are often more valuable than patents for large battery plants.

4. Industrial Design Protection
